Boston is currently on lockdown as police continue the manhunt for Dzhokar A. Tsarnaev, the 19-year-old suspect in the Boston Marathon bombing investigation. No people out and about makes for a pretty eerie scene in the town. Here are 15 pictures taken by people and uploaded to Twitter and Instagram to give you an idea of how Boston looks right now. It's pretty bananas. Have a look.
6:55 AM ET: The AP is reporting that the suspects are from Chechnya, and have lived in the US for at least one year. The surviving Boston bomb suspect has been identified as Dzhokhar Tsarnaev, 19, of Cambridge, Ma. NBC News is reporting that both suspects are brothers. Sources say that the men may have military experience, according to law enforcement officials.
6:30 AM ET: CNN is reporting that officials are worried that the suspect who remains at large could have explosives on his body. An official tells the network that the suspect killed overnight had explosives on his body. As a result, city officials have suspended all public transportation for the time being. Those in Watertown and the surrounding neighborhoods are being urged to shelter in place until further notice. Many colleges have cancelled classes for the day. Businesses are being told not to open.
